Application filed April 10, 1914. Serial No. 830,884.

To all whom it may concern:

Be it known that I, S'mmsmw Knawozrn, a subject of the Czar ofRussimresiding at Bulfalo, in the county of Erie and State of New York,havejinvented certain new and useful Improvements in Life-Boats, ofwhich the following is a s ecification.

This invention re ates to certain new and useful improvements in lifeboats.

The primary object of this invention is to provide a life boat that isincapable of sinking and'pro'vided weights adapted for adjustableinsuring against capsizing.

A. further object is to provide a life boat impossible of capsizing orsinking and provided with means for assisting the rescue of drowningpersons from the water and v with a wave deflecting guard for the deck.

A still further object is to provide a rigid internal frame-work for ahollow life boat in a structure that is non-capsizable and provided withlaterally inflated wave deflecting 'uards.

depths and a lVith these general objects in View and others that willappear as the nature of the invention is better undestood, the sameconsists in the novel combination and arrangement of parts hereinafterfully described, in the accompanying drawings,

out in the appended claims.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts 35 throughout theseveral views:-F1gure 1 15 a perspective View of the complete 'device..Fig. 2 is a top plan View thereof with the rail removed, and portionsbeing broken away; Fig. 3 is a central transverse seean elevation viewof either end of the device, the hoisting chain being removed. Fig. 5 isa detail side elevation of the ballast frame spring catch, parts of thesame being broken away. -Fig.

a vertically-ad ustable ballast struction of member.

Referring more in detail to the drawings,

55 the lifeboat consists of the hollow hull 10 having internal bracingribs 11 arranged as with ballasting overboardlthe sloping top ballastball disclosed in Fig. 2 and with transverse brace rods 12 positionedslightly beneath the deck 13 while upright supports i f are positioned.between the keel portions of the braces 11 and the longitudinal centralbottom support 15 of the deck.

A railing 16 surrounds the entire deck and is preferably in the form ofa grating 17 and havingpositioned adjacent its point 0 mounting upon thedeck, with hand-hold straps 18 substantially T-shaped in crosssectionand arranged oppositely at each end portion of the boat. Intermediatesaid hand grip members 18, the-railing is proyided with a strap 19having a cut-away bottom edge 20 and adapted to allow the water from thedeck to freely flow outwardly and'over 21 of hollow side wings 22 whichhave bottom deflecting slightly convexed faces 23. Bails 'or bow-shapedframes 24 have their separated on s 25 pivoted as at QG at oppositepoints uporrthe boat hull 10 and preferably at points between the wings22 and hand grips 18.. Said bails 2a are made adjustable in lengthby theemploy ment of slots 27 in the lower portions 28 thereof which areoverlapped upon the upper ends 25', the latter being provided with bolts29' engaging within said slots. Ballast iweight balls 30 are removablysecured to the lower freeiends of said bail portions 28 by means of twobolts 31 as best disclosed in Fig. 7, and whereby it will 'be evidentthat by removing said bolts, the ball 30 maybe removed, from thesupporting bail,-and such ball is adapted to be then placed within thecage or inclosure 32 formed upon the deck of theboat by means of theupright posts 33.

End projections 3a of the deck 13 extend outwardly of the hull and areeach provided with a-swinging hook adapted. for 'recep tion within oneof the perforations 36 in the bail members 28' when 'the ball 30 is removedtherefrom, and whereby the bail is retained in its elevatedhorizontalposition as illustrated in Fig. 6. A chain 37 is secured in astaple 38 of the extension Stand being attached to a similarstaplc uponthe ball weight 30. It will be seen that the bail may be readily pivotedto its horizontal position by pullingupwardly upon the chair; 3'? whilethe ball may then be readily removed and placed within the iuclosurc andthe bail hooked into position as illustrated.

. When lowering the bail and the bi'lllfirl] balls, it becomes desirableto retain the same in their lowered position for normal use and for thispurpose, the latch members best illustrated in Fig. 5 are employed inconnection with each pivoted end 25 of the bail members. Said ends areprovided with projet-ting lugs 40 having outer beveled faces ll andtransverse perforations 42 While a spring-pressed 1 latch 48 having abeveled lower face 44 is adapted to. engage within said perforationswhen the bale assumes its loweredsubstantially vertical position withthe carried ballast weight 3-0 at its extreme depth while the slot andbolt connection at the overlapped portions of the bail members allowsthe length of the bail to be slightly regulate In the modifiedconstruction illustrated in Fig. 8, the boat bottom fiOis provided witha circular perforation 51 having an upwardly-extending casing orthimbl'e 52 secured around'the same and positioned between said bottomand a deckmember 53. A. red is slidably mounted within the thimble andis provided with a ballast weight .35 onthe lower end thereof while itsu ppcr end is toothed as at 56, and where by a ;-revolving of the gearwheel 57 which meshes therewith is adapted to raise or lower the rod andthe ballast member, it being noted that a crank arm 58 is preferablyemployed for turning the gear 57 while a pawl 3: 9 engages the gearwheel for preventing the lmvering of the rod when desired.

lVhile the forms of the invention herein shown and described are whatare believed to be preferable embodiments thereof, it is nevertheless tobe understood that various forms anti modifications thereof may be hadwithout departing from the spirit and scope of the invention as claimed.

What is claimed as new is 1. In a device of the class described, ahollow hull, a grating railing surroundingthe deck portion of the hull,oppositely-arranged T-shaped hand hold members outwardly projectin fromthe railing at both ends of the hull, hollow "wave deflecting Wing'soppositely arranged between said hand-hold members, adjustable bailsextending beneath the hull and pivoted to the latter at opposite pointsbetween said wings and hand-hold members, ballast balls removablysecured to the lower ends of said bails, hoisting chains connectedbetween said bails and the ends of said hull, and normally-positioningspring latches carried by the hull and adapted for engaging said bailsin their lowered positions. I r

2. A device of the class described, comprising an airtight hull, agrating railing extending around the same,'outwardly-ex- -tend1nghollovs 'ivave deflecting wings oppositely positioned upon thegniddlcportion of said hull, sald wlngs having downwardly sloping upper andconvex lower faces, and

T-shaped hand-hold bars secured to said railing and adjacent to each endthereof.

3. A device of the class described, comprising in combination with ahollow hull having deck extensions at each end thereof, of bailsadjustable in length having their ends pivoted to opposite sides of thehull, ballast v'fieights remo'vably secured to said bails," chainconnections between said weights and deck extensions, projectingperforated lugs upon said bails and springpressed latches upon the hulladaptedfor engagement with the perforations of said lugs upon the loweroperative positionsof said bails.

4. A device of the class described, comprising an air-tight hull, agrating railing extending around the same, outwardly-extending-hollowwave deflecting wings oppositcly positioned upon the middle portion ofsaid hull, said wings having downwardly sloping upper andconvex lowerfaces, T- shaped hand-hold bars secured to said railingand adjacent toeach'end thereof, and

. vertically-adjustable ballast devices carried by the hull. I

In testimony whereof I affix my signature .in pres nce of two witnesses.
